who has a tune on a 2015 turbo s, who is the tune from and what are your thoughts overall from stock to tune, thanks

BOOSTED TTS

I have a 14' and you can't go wrong with Cobb, the best customer service and technology, call Sam he will hook you up!!! Had Cobb on my 997.2 TTS and know on the 991.1 TTS.

Go with Cobb, especially if you put an aftermarket exhaust. They can custom tune your file based on your equipment with data logging.

My Europipe equipped Turbo S ran even smoother and faster after some data logging and custom tune.

COBB for the win

there is only really 2 options,
GIAC or COBB

Cobb gives more flexibility and has shown the best results thus far

I have a 16' and you can't go wrong with Cobb, the best customer service and technology, call Sam he will hook you up!!! I have the Kline exhaust as my only add on. Using Cobb and Sam map, the biggest difference i see is the spool up time, jumps to 17.

Sam, do you have any updates on the progress COBB is having with the 991.2 TTS? Any ETA?

Hi!

It's getting closer on the 991.2. I think we will see a few options this quarter.

Champion / GIAC already have a tune!

COBB is a system/tool and offers generic files or files written for other customer cars. Saying COBB is the best is a somewhat inaccurate, best in what? it all depends on the tune you are using and who wrote it. I use a COBB myself, from a practicality perspective it is outstanding, but it is as good a program as how well it was customized to your needs, fuel, hardware, temps, elevation, usage, etc.. A COBB or GIAC or Bydesign, EVOMS, Protomotive, Champion, FVD generic off-the-shelf files will all be more or less the same, there is no better or worse, all are knowledgeable people. Once you move to a customized tune, then difference starts appearing, and a better acceleration performance doesn't mean that one program is better than the other. It could be as simple as a file with more boost than another, great for straight line and Q Mile, but once you put it on a race track it can perform worse than stock after few laps, if EGTs get out of control, timing is pulled back or AFRs go too rich to compensate for heat.
